A method for manufacturing a secondary battery includes a formation step for charging an assembled secondary battery to a state of charge (SOC) of 45% to 65%; an aging step for aging the secondary battery for which the formation has been completed; and a low voltage testing step for measuring the change in voltage value, wherein, in the low voltage testing step, a voltage value is measured in an SOC interval of 30% or lower. Since an SEI coating is stably formed in the method for manufacturing a secondary battery, charging time is shortened and thus the secondary battery can be mass-produced. In addition, since a low voltage test is performed in an interval in which the voltage change rate per capacity of a negative electrode is high, a low voltage defect due to non-uniformity of the formation process can be detected in the method for manufacturing the secondary battery.

The disclosure an air conditioning system and a method of controlling the same. During the heating operation of the A2W indoor unit, the A2A valve that connects the outdoor unit to the A2A indoor unit is closed to prevent the inflow of the refrigerant into the A2A indoor unit, so it is possible to prevent performance degradation by improving performance loss due to refrigerant bypass to a stationary A2A indoor unit. In addition, in order to improve the performance due to deterioration of heating performance, the system itself can cope with a control algorithm without any additional hardware configuration, thereby minimizing the installation cost.
